The Squishy Trend

I wonder if any student can explain the trend to me now? I can pretty much see students in uniform, each holding a squishy as they walk around the shopping mall.

Kinda feel out of control, as squishy are meant for people with special needs to have something to distract them and/or something to help them to concentrate. But all the suddenly, every kid seems to have a need for it.

And you need to have one to be part of the pack.
